1498. Your vessel is on course 180°T speed 22 knots. The apparent wind is from 70° off the port bow, speed 20 knots. What are the true direction and speed of the wind?

The true wind direction and speed are found by vectorially adding the ship's velocity and the apparent wind. Resolving each vector into north-south and east-west components, then summing those components, yields a true wind from 051T at 24 knots.
